IGNITER WITH SPARK-EMITTING MASS.

Specification of Letters Patent. Patented Jll. 31, 1911.

Application filed October 21, 1909. Serial No. 523,839.

To all whom 'it may concern:

Be it known that I, JACQUES KELLERMANN,

manufacturer, citizen of Hungary., subject of the King of Hungary andEmperor of Austria-Hungary, residing at Berlin, in the Kingdom ofPrussia and Empire of Ger; many, have invented new and usefulIniprovements in Ignite'rs with Spark-Emitting Masses, of `which thefollowing is a speciiication.

My invention relates generally to igniters of that kind in which sparksare produced by friction and transmitted to a combustible body, such asa slo\v- 1nat`ch or a wick saturated With liquid fuel, and particularlyto that kind of igniters in which the sparkeinitting mass is formed by ametalor alloy which scintillates when rubbed or scraped such asparticularly, the alloys of cerium and the like.

A primary object of my invention is to provide igniters of the abovedescribed kind in which the arrangement of the sparkeniitting body andthe harder rubbing or scraping body is such that these are located in aparticularly favorable position relatively to the combustible body forigniting the latter at the moment When sparks are emitted. To this end,I preferably arrange the rubbing or scraping body such as a sharpenedpiece of steel close beside the coinbustible body, whereas l arrange thesparkemitting mass in such a manner that it 4can be moved relatively tothe scraper and the sparks produced fall onto the` combustible body. lnorder to assure that the sparks impact the combustible body in thismanner, I prefer to arrange the igniferous parts in such a positionrelatively to the combustible body that the direction of motion whileproducing sparks by friction must cut the Zone of the flame to beproduced.

Further, for assuring' the transmission of the sparks to the combustiblebody it is important to arrange that'at'tliemomen-t. of ignition thespark-emitting mass, such as a pyrophorus alloy or the like, is locateddirectly at or close lto the combustible body,

'it being indifferent Whether it is moved, or

the scraper, or both simultaneously., For obtaining the same action,further, according to my invention I prefer to arrange the ,one of thevparts required for producing sparks, preferably the scraper, in a cham?ber in which the fuel evaporating from the combustible body collects ingaseous form when the igniter is closed, so that the sparks producedwhen rubbing said part With the otherA part required for producingsparks,n

preferably the pyrophorus metal, are produce-d in this chamber itselffilled with combustible gases, and consequently these gases are igniteddirectly and on their 4part can ignite the fuel on the Wick.

A further object of my invention is to provide haildy, durable ignitersof this kind Which can be manufactured cheaply.-

- Additional features of my invention will be understood from thefollowing specification in connection with the accompanying drawings andfrom the claims.

Figure l is a longitudinal section through a closed pocket-igniterhaving automatic ignition; Fig. 2 is anend elevation of tlie same; Fig.3 is a longitudinal section of thethis end, on the aXle\ around Whichtie lid rotatesy isA arranged a' loose friction Wheel driven by meansofla pawl When the lid opens. The loose arrangement of the Wheel causesit to be driven only in the one direction, z'. e. when opening the lid,vvherea'sit remains stationary when closin the lid s 'o that no sparksare produced uring this movement.

Referring to the drawings, the lid 41 1s connected with the bottom part42 of the casing by an axle 43, on Whichwis a loose Wheel 44 of steel orthe like having on its periphery two kinds of toothing beside oneanother. Toothing 45 corresponds to .the ribs or teeth of a iile andserves for scraping the pyrophorus mass, Whereas the secon toothing 46comprises ratchet-teeth. 4In theA part 45 of Wheel 44 so that ignitiontakes place certainly even when pin 50 wears.

In the form according to vIigs.' land 2 there serves as abutment forspring 51 a screw, 58, after removing which spring 52 lio and pin 50 canbe readily removed through i the contrary, Amovable from the casing 42is provided the hole 54 in casing 42 and exchanged. In l thisconstructional form the fuel reservoiri is formed by casing 42 itself.In the cong structional form according to Fig. 3, on

a special fuel reservoir 55 rethereby enabling small repairs to be made|l easier. In this instance tube 5l for the' pyropho'rus pin 50 is builtinto the fuel reservoir itself and traverses the saine. As abutment4 forspring 52 leaf spring 56 serves which holds the lid 41 in its closedposition. A similar spring 56 is also provided in the forni according toFigs. l and 2.

For opening the lid autoinaticallyaspring i 57 is arranged on the rearWall of casing j 42 beside the fuel reservoir; this sprin is 5 shownbroken olf in Fig. l but in reality I presses against lid 41 in themanner readily understood from Fig. 3, so that by pressing l on button58 of the spring 56 or 56 lid llis released and is subjected to theaction of spring 57. Wheel 43 is driven byV its; engagement With paivl45T and the file-like partof the same turns against the y rophorus pinforming sparks Which fly onto the wick 59. Instead of this wick animpregnated slow-match can be einplowed when, obviously, the fuelreservoir can be omitted, or I may arrange slow-match and l' wicksaturated with fuel beside one another f in the same ivniter. y Byarranglng the file-Wheel directly on the axle of the lid and employingthe paWl, the intermediate gearing required otherwise is superfluous,the mechanism is simplied, l and the igniter cheapened and made lighter.l Also it is possible only in this manner to i use one single Wheel forproviding the ratchet-teeth and the file-teeth or ribs, mali ing aspecial coupling superfluous. In- ,i

stead of the metal file-Wheel I may, however, employ a stone Wheel forproducing sparks. y

Having now described my invention what I claim and desire to secure byLetters Patcnt of theUnited States is:

l. In an igniter, the combination with a casing, and a cover, of an axlepivotally connecting the cover with the casing, a scraping Wheel on saidaxle, means whereby movement of tlre cover will cause rotation of theaxle, and a pyrophorus body bearing upon the scraping Wheel.

2. In an igniter, the combination of a. casing, a cover therefor, anaxle pivotally connecting the cover to the casing, a scraping wheel onsaid axle, a ratchet Wheel on the axle, a spring-pressed paWl carried bythe cover and engaging said ratchet Wheel, and a pyrophorus body Withinthe casing bearing against the scraping Wheel.

In a pocket-igniter a casing, a com-. bustible body Within said casing,a cover for said casing, an axle for pivotally connecting said coverWith said casing, a scraping wheel loosely arranged on saidaxle, a pawlarranged Within said cover, a spring pressing said paivl into engagementlwith said Wheel When the igniter is closed.

4. In a pocket-ignitcr a casing, a conlbustible body Within said casing,a cover for said casing, an axle for pivotally connecting said coverwith said casing, a scraping wheel loosely arranged 011 said. axle, twokinds of toothing beside one another on the periphery of said Wheel, theone. kind corresponding to the ribs of a file and the second toothingcomprising ratchetteeth, a pawl pivotally arranged Within said cover andengaging'said ratchet-teeth, a locking device for said cover, a springpressing against the inside of said cover and tending to open it.

In testimony whereof I have hereunto setmy hand in presence of twosubscribing Witnesses.
